Sebelius will meet with Austin Mayor Lee Leffingwell and San Antonio Mayor Julian Castro on Friday.

A statement from her office says Sebelius will highlight the ways Texans can learn about the Health Insurance Marketplace.

Critics are calling for Sebelius to resign because the federal website designed to help people buy health insurance is still not working more than three weeks after it launched. The online health insurance exchange is supposed to allow the uninsured buy affordable health insurance and in many cases receive government subsidies.
